Excavator Bucket Attachment Device

Abstract

A removeable attachment to an excavator bucket allowing for multi-purpose use of a single excavator without the need for lengthy modification or installation. The preferred embodiment is a grading blade attachment. The invention attaches to an excavator bucket by drilling holes into the bucket, inserting the coupling device of the invention between the bucket, and inserting a metal pin through the bucket and coupling device. The metal pin is secured by a lynch pin when installed. The attachment also has a circular piece of metal, allowing for the attachment to pivot with the contour of the ground during use and allowing more accurate use of construction cleanup equipment while reducing damage to landscape.

I claim: 
     
         1 . An attachment device comprising:
 A coupling, having a rectangular piece of metal that has a width slightly less than the width of the inside of a standard excavator bucket, having a top portion and a bottom portion;   A piece of heavy wall tubing attached to said top portion;   A hole in the middle of said bottom portion;   Said coupling secures to said excavator bucket by inserting said top portion of said coupling device inside said excavator bucket, inserting a metal pin through holes in the side of said excavator bucket and through said heavy wall tubing, and securing said metal pin by inserting a lynch pin into said metal pin;   An attachment that attaches to the coupling device.   
     
     
         2 . An attachment device as in  claim 1 , wherein said attachment has a circular piece of metal, said circular piece of metal housing a spring pin, and said attachment is removably attached to said coupling device by applying pressure to said spring pin to compress said pin, inserting said circular piece of metal through said hole in said coupling device, and releasing pressure from said spring pin. 
     
     
         3 . An attachment device as in  claim 2 , wherein the attachment is a grading blade as commonly understood in the construction industry. 
     
     
         4 . An attachment device as in  claim 3 , wherein said grading blade has having a front portion and a back portion;
 A circular piece of metal welded to the center of said front portion of said grading blade; and   A rectangular enclosure attached to said back portion that has an opening slightly wider than the width of a standard excavating bucket and having the opening facing away from the bladed part of the grading blade.   
     
     
         5 . An attachment device comprising:
 A coupling, having a rectangular piece of metal that has a width slightly less than the width of the inside of a standard excavator bucket, having a top portion and a bottom portion;   A piece of heavy wall tubing attached to said top portion;   A hole in the middle of said bottom portion;   Said coupling secures to said excavator bucket by inserting said top portion of said coupling device inside said excavator bucket, inserting a metal pin through holes in the side of said excavator bucket and through said heavy wall tubing, and securing said metal pin by inserting a lynch pin into said metal pin;   An attachment that attaches to the coupling device;   said attachment has a circular piece of metal, said circular piece of metal housing a spring pin, and said attachment is removably attached to said coupling device by applying pressure to said spring pin to compress said pin, inserting said circular piece of metal through said hole in said coupling device, and releasing pressure from said spring pin.   
     
     
         6 . An attachment device as in  claim 5 , wherein the attachment is a grading blade as commonly understood in the construction industry. 
     
     
         7 . An attachment device as in  claim 6 , wherein said grading blade has having a front portion and a back portion;
 A circular piece of metal welded to the center of said front portion of said grading blade; and   A rectangular enclosure attached to said back portion that has an opening slightly wider than the width of a standard excavating bucket and having the opening facing away from the bladed part of the grading blade.   
     
     
         8 . An attachment device comprising:
 A coupling, having a rectangular piece of metal that has a width slightly less than the width of the inside of a standard excavator bucket, having a top portion and a bottom portion;   A piece of heavy wall tubing attached to said top portion;   A hole in the middle of said bottom portion;   Said coupling secures to said excavator bucket by inserting said top portion of said coupling device inside said excavator bucket, inserting a metal pin through holes in the side of said excavator bucket and through said heavy wall tubing, and securing said metal pin by inserting a lynch pin into said metal pin;   An attachment that attaches to said coupling device;   Said attachment has a circular piece of metal, said circular piece of metal housing a spring pin, and said attachment is removably attached to said coupling device by applying pressure to said spring pin to compress said pin, inserting said circular piece of metal through said hole in said coupling device, and releasing pressure from said spring pin;   Said attachment is a grading blade as commonly understood in the construction industry.   
     
     
         9 . An attachment device as in  claim 8 , wherein said grading blade has having a front portion and a back portion;
 A circular piece of metal welded to the center of said front portion of said grading blade; and   A rectangular enclosure attached to said back portion that has an opening slightly wider than the width of a standard excavating bucket and having the opening facing away from the bladed part of the grading blade.
